{wiki=Communication_Theory_of_Secrecy_Systems}
The Communication Theory of Secrecy Systems, primarily discussed by Claude Shannon in his foundational work on cryptography and information theory, provides a systematic approach to understanding how information can be securely transmitted over insecure channels. The key elements of this theory include the following: 1. **Information and Uncertainty**: At the core of the theory is the concept of information as a measure of uncertainty. Shannon introduced the idea of quantifying information using bits and entropy, which measures the unpredictability of information.
